Softboxes

I have a 120cm/47″ Octagon Softbox with grid
These are currently £45 on eBay.co.uk

I also use 2 rectangular 60x90cm Softboxes with Grids. I got mine for US $43.98 (approx £26) each on eBay.co.uk, but they seem to be currently out of stock. The next best I can find is this one on eBay.co.uk, which is £32 plus £12 postage.

Flash holder/light stand adapter

To attach the softbox and flash to a light stand, I use a Black Adjustable Flash/Shoe/Umbrella Mount/Holder/Bracket. These are £7.28 from the seller ukpartsdeal on eBay.co.uk

Remote Cable Release

To trigger the camera remotely (to avoid camera shake) and also to use for taking time lapse sequences, I use the Yongnuo MC-36 C3 Camera LCD Timer Control Shutter Remote (for 5DII and III, 7D and various others). This is currently £19 on amazon.co.uk
